To a-ZZ whom it muy concern;

Beit known that waWA'rsoN A. GOODYEAR and Linnen Knronnn, both citizens of the United States, and residents, the former of New Haven, in the county of New Haven and State of Connecticut, and the latter of Sangatuelr, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Devices for Regulating the Feed and Discharge of Liquids in Heating or Cooling Vessels, of which the following is a specification.

Our invention relates to an improved forni of deviee for automatically feeding and discharging any forni ot' open vessel through which a constant stream of liquid is desired to be passed without danger of overiiowing; and by means thereof it is possible to regulate the supply and discharge ofl vessels of all sizes to Variable pressures of liquid in the supply-pipe. Our invention is, however, primarily applicable to all forms of apparatus for heating or cooling water for domestic purposes, and more especially to the various forms of Water-heaters invented hy us for which Letters Patent 0i' the United States have heretofore been granted to us or for which We have applied for patents.

The invention Will be best understood by reference to the accompanying sheet of drawings, in Which- Figure 1 is a vertical cross-section of the device attached to an ordinary cylindrical-heating or cooling Vessel; Fig. 2, a plan View of the saine, and Fig. 3 a sectional detail showing the supply and discharge cocks and cheekvalve.

Similar letters refer to similar parts throughout the ser eral views.

In both Figs, 1 and 2, R represents a heating or cooling vessel of any desired fornhn-hieh is or is not open ou top, according to circumstances.

G represents the discharge-pipe at the bottom of the vessel, and G the supply-pipe entering at or near the top.

The invention consists in so arranging the supply and discharge pipes in reference to each other that as much liquid is admitted to the vessel in a given period of time as is discharged therefrom in the same time, and in providing, in combination with the supplypipe, a device for reducing the ordinary pressure of the Water in the pipes'at the point where the apparatus is set up to such pressure as will oause a regular flow through the same. This is accomplished, as shown in the dra-W- ings, loy arranging the supply-pipe G', which leads from the usual supply-pipe, in such a manner that it shall pass in close proximity to the discharge-pipe G, and by placing between the pipes and in both pipes a double discharge and supply cock, H, composed of valves having `Water-passa-ges of equal dimensions, arranged to turn upon the saine horizontal spindle, N.

ff represent the valve-seats in the spindle, and are of the shape there shown.

Fig. 1 shows the Valve in the supply-pipe G in vertical cross-section, and Fig. 2 the arrangement of thetwo pipes G and G".

F is an ordinary handle, by means of which the cook H is turned.

In many cases the inward pressure of the liquid is so strong that more Water would enter through the valve in the supply-pipe than can he discharged through G, and there is danger of the vessel overliowing. To obviate this difficulty a regulating or cheek valve, V, of any convenient character, sueh asis ordinarily used in Water-pipes, is inserted in the supply-pipe G, for retarding the iiow of the water iu the pipe. This cheek-valve may he set by means of a Wrench or turning-Sorenr or by any other convenient forni of device.

The method of operating the device is suhstantially as follows: lVhen the apparatus is first set up, both inlet and outlet valves are opened to their full extent by turning the haudle F so that it shall be parallel with the diseharge-pipeG. Theeheek-valve is then opened hy turning it, and the exa-et position ascertained at which, after having been set, it Will allow a maximum amount of Water t0 pass through the vessel B and the two valves with out danger of overflow. The Wrench or handle used for turning it may then be removed andthe flow regulated by means of the handie F. The connection between the supplypipe G' and the permanent supply-pipe may be made in any convenient manner, and the device may be constructed of any convenient 5 material.

We claim as ourinvention- 4In an apparatus for heating or cooling liqnids, the combination, substantial] y as hereinbefore set forth, of the vessel R, the supplyxo pipe Gr', provided with the check-valve V, and the double supply and discharge cock H, whereby as much liquid is admitted to the vessel asis discharged therefrom in the same time. Signed at the city and county of New` Haven,

in the State of Connecticut, this 28th day of 15 January, 1886.
